What Brain DoesThalamus- decides where to send incoming sensory data (fromeyes, ears, mouth, skin)Sensory cortex- interprets sensory dataHippocampus- stores and retrieves conscious memories; processes sets of stimuli to establish contextAmygdala- decodes emotions; determines possible threat; stores fear memoriesHypothalamus- activates "fight or flight" response

Process of Creating FearThis is called the low RoadTake No ChanceConsidered DecisionThis is called High Road

The endocrine system uses blood vessels as information channels. Glands release into the bloodstream specific chemical messengers called hormones..

The typical endocrine organ is a ductless gland that secretes chemical mediators directly into local blood vessels. to regulate the target organ's function. Hormones are also instrumental in regulating mood, growth development, tissue function, and metabolism, as well as sending messages and acting on themTwin action of Fear StimuliFear Necessity?Fear and ExcitementMany people enjoy being afraid -- the arousal that comes with the fight-or-flight It's no wonder so many people go to see scary movies and ride roller coasterson dates.SurvivalIf we couldn't be afraid, we wouldn'tsurvivefor long. We'd be walking into oncoming traffic, stepping off of rooftops and carelessly handling poisonoussnakes. In humans and in all animals, the purpose of fear is to promote survival. In the course of humanevolution, the people who feared the right things survived to pass on their genes. In passing on their genes, the trait of fear and the response to it were selected as beneficial to the race. He concluded that the entire fear response is an ancient instinct that has been untouched by the nuances of modern civilization.

It serves the same purpose today as it did when we might run into a lion while carrying water back from the river. Only now, we're carrying a wallet and walking down city streets.

Common FearsMost common fears .The top 10 list goes like this:Terrorist attacksSpidersDeathFailureWarHeightsCrime/ViolenceBeing aloneThe futureNuclear war

Overcoming fearFear extinction involves creating a conditioned response that counters the conditioned fear response. While studies situate the amygdala as the location of fear memories formed by conditioning, scientists theorize that fear-extinction memories form in the amygdala but then are transferred to themedial prefrontal cortex(mPFC) for storage. The new memory created by fear extinction resides in the mPFC and attempts to override the fear memory triggered in the amygdala.

Practical Tips to overcome FearIt doesn't matter why you're scared. Learn about the thing you fear. Train. Find someone who is not afraid Take her/him along when you try to conquer your fear -- it'll be much easier.Talk about itPlay mind games with yourself. Stop looking at the grand scheme. Seek help.
